Say in a field called 'Subject' contain five 5 records: Maths, English, Product Design, Business Study, and Art How can I use a combobox to show all these records and let user select each one? if this is impossible, is there an alternative appoach? Thanks

1.加入 TComboBox 的 Items 屬性中 ComboBox1.Items.Add('Maths'); ComboBox1.Items.Add('English'); ... 2.使用者選取了哪個: ComboBox1.Items[ComboBox1.ItemIndex];    --- 每個人都是一本書

don't understand this one: 2.使用者選取了哪個: ComboBox1.Items[ComboBox1.ItemIndex]; <---

the combobox show the data i need, but how can I relate it to the table? say the table name is : tSubject (ADOTable)

1.ComboBox1.ItemIndex; 指現在 ComboBox1 所顯示的 Item 的 Index 2.不太明白您的意思？還是您要用 TDBComboBox？    --- 每個人都是一本書

should i use a tbcombox then?? because the data avaliable in the combox has to be related to a table

您要怎麼個 related 法？ 可以說明清楚一點嗎？    --- 每個人都是一本書

that means it shows whatever options is avaliable in that field column... ex. Name _______ Frankie Jacky Mary Then under the dbcombox, it should show Frankie, Jacky and Mary options as well. If an extra record is added under that field, the dbcombox should be update at the same time. can i do that?

您得手動把該 Table 內的 record 加到 ComboBox 內.    --- 每個人都是一本書
